Hi @siva172902,
I hope you are doing well
My apology for the delayed response.
Kindly check the Kernel command line (bootargs) is set as per your board.
One can reference the section 6.2.2 Kernel command line (bootargs) from the Android ™ User's Guide.
If it does not solve the issue, kindly share the values of your Uboot environment variables using the 'printenv' command for further debugging the issue.
Thanks & Regards,
Dhruvit Vasavada
